Head unit install confusion

[SuRrEaLNJ]

alright, first off i have to admidt I feel like an idiot. ive passed the electrical ASE, yet this stupid head unit has the best of me.

i Hve a jvc AM/FM CD player im tryin to wire into the 91, i got the harness adapter for it and nothin seems to be lining up right

heres what i know
ground = blk
12v ignition= yellow/blk stripe
12v constant= green/yellow stripe
dash dimmer= blue/red stripe
and the blue goes to power the factory amp...
red = ???
yellow=???

now im pretty sure i have the wrong adapter for the powerd conector but im prettysure i have the speakers right. eitherway i have power to the uinit, but no output.

I beleive the unit is a JVC KD-G120 and i know the truck dosnt have an amp or sub in it, so im asuming that ment it had the base radio from the factory

anybody know what has to go to what, or what harness i need to make this work right?

Amp Remote Blue/White
Left Front (+) White
Left Front (-) White/Black

Left Rear (+) Geen
Left Rear (-) Green/Black
Right Rear (+) Violet
Right Rear (-) Violet/Black


here is a link to a pretty good diagram.
